LIGHTING FIXTURE 7 Harry E. Rutledge, Dormont, Pa. Application September 20, 1939, Serial No. 295,774

6 Claims.

This invention relates to improvements in lighting fixtures, and more particularly to a unitary mounting for a multiple lighting fixture.

In the illumination of gasoline service stations and the like, the working areas and equipment thereof are commonly lighted by overhead lights. For example, it has been the practice to employ what are known as island lights for illuminating the gasoline pumps and the islands upon which they are positioned, together with the surrounding driveway areas.

Also, it is common practice to employ overhead floodlights for the illumination of the exterior of buildings, for signs and for other equipment.

My invention contemplates mounting one or more of such floodlights atop an island light by means of a unitary mounting which supports the island light reflector and the floodlights thereabove, the entire assembly being carried by a single pole or standard.

I further have in view to provide a mounting of the character stated which willhave minimum interference with the emitted light, which will support the floodlights without injury to the reflector of the island light, which is sealed against the ingress of rain and moisture, and a mounting which is readily and selectively adapted to the addition of one or more floodlights without altering the character of the mounting.

Additional objects and advantages will become apparent from the following description taken in connection with the accompanying drawing, wherein:

Fig. 1 is a top plan view of a multiple lighting unit embodying my invention;

Fig. 2 is an elevational view thereof;

Fig. 3 is an enlarged sectional view thereof on the line III-HI of Fig. 2;

' Fig. 4 is a detail sectional view on the line IV-IV of Fig. 3; and

Fig. 5 is a detail sectional view on the line V-V of Fig. 1.

Referring to the drawing, the multiple'lighting unit includes an island light generally designated A, and one or more floodlights designated B.

The island light A includes a wide open-bottom reflector 2 usually formed of thin sheet metal provided with a suitable inner reflecting surface. The contour of the reflector 2 is such as to direct the light rays from a source or bulb ,3 downwardly and outwardly in a laterally spread beam. Thus, upon elevating the light A above the pump island of a gasoline station, the pumps,

The floodlight or lights B may be of any suitable construction including a casing or housing 4 containing a suitable source of illumination.

' Floodlights of the character contemplated are 5 well known, and provide a diffused spread beam of light suitable for illuminating large areas with a more or less uniform intensity.

For the purposes of mounting the island light A and. one or more floodlights B as a unit, I provide a base member or pole socket 5 in the form of a hollow sleeve having one or more set screws 6 for securing the same to the upper end of a vertical pole or standard 1.

The pole socket 5 contains a standard electric socket 8 for the island light bulb 3, which electric socket is supplied by main wires 9 concealed in the pole 1 and connected with a suitable source of current.

Extending from the pole socket 5 are a plurality of arms Ill, three being shown, said arms being equally spaced and extending outwardly from and upwardly beyond the pole socket, having vertical portions II and threaded terminals I2. Each threaded end I2 has a nut I3 providing an annular series of abutments for receiving and supporting the island light reflector 2. The arms I0 may be secured to the socket 5 in any suitable manner, as by the threaded connection shown. v

Said island reflector is apertured to receive the several arm terminals I2. I4 designates fiber or rubber sealing. washers disposed on either side of the reflector 2 at said apertures for sealing against rain and moisture at the points of connection with the arm terminals I2.

The threaded terminals I2 of arms I0 extend upwardly through and beyond the body of the reflector 2, and may be provided with nuts I 5 for securing the reflector at any arm where it is not desired to mount a floodlight unit B. (Fig. 5.)

Arms I 0 are relatively small in cross-section and due to their being spaced laterally beyond the light source 3, do not materially interfere with the light rays therefrom. Likewise, due to the lateral disposition, of the arms, they engage the reflector 2 outwardly beyond the central upper portion of the reflector and therefore do not interfere with the reflection of light from said reflector portion.

A still further advantage is attained by the outward disposition of the arms I I], or more particularly their vertitcal portions II, by which the floodlights B may be mounted, either singly or in plural. Thus the terminals I2 of said arms island and driveway will be illuminated thereby. are widely spaced to permit the attachment of a series of the floodlights B with ample room for independent swinging or pivotal adjustment of the latter.

For the purpose of electrically connecting one or more of the floodlights B, the arms I!) are hollow to accommodate wiring l6 which may be connected in the main electrical circuit of wires 9, as will be readily understood.

I prefer to provide an adjustable mounting for the floodlights B so that the same may be properly directed toward the object or objects to be illuminated thereby.

To this end, this mounting includes an internally threaded sleeve member I! attached to the terminal end l2 of an arm It as in Fig. 3, and a bracket I8 attached to the case 4 of the floodlight B.

Sleeve l7 and bracket I8 are each provided with complemental annular clamp portions I9 and 20 respectively, said portions interfitting to form a rotatable adjustment or hinge device for vertical adjustment of the light B. A thumb screw 21 is passed through one of said complemental portions and engages a threaded boss'22 in the other for securing the members 7 l1 and H3 in fixed relation at the desired angle of adjust ment.

Members I! and [8 are hollow, as are their clamp portions l9 and 20, whereby the wires It may be extended from the hollow arm ID into the casing 4 of the floodlight B for attachment to the usual socket 23 in the casing.

By rotating adjustment of the sleeve I1 and nut [3, the floodlight B may be rotated horizontally for adjustment thereof, which, together with the adjustment of the clamp l92ll, provides an universal adjustment permitting the proper positioning of the floodlight in relation to the object or objects to be illuminated thereby.

Attention is directed to the fact that the mounting herein set forth provides a stable unitary support for both the island light and one or more floodlights without subjecting the thin metal reflector 2 to the weight of the floodlights, and without such mounting interfering with the emitted light from the multiple unit.

Also, the mounting of the floodlights does not endanger the light source 3 of the island light, as by rain and moisture, since the attachment of the floodlight is spaced laterally of the said source 3 and is sealed at the region where the same passes through the reflector 2.

Various changes and modifications are con templated within the scope of the following tending outwardly and upwardly from the pole socket engaging the reflector laterally beyond the light source for supporting the reflector, at

least one of said arms extending through the reflector for supporting a second lighting unit atop the reflector, a second lighting unit, means for variably adjusting and securing said second lighting unit on said arm consisting of a rotatable sleeve member connecting the second lighting unit with an intervening hinge joint, said means and arm being hollow, and an electrical connection for the second unit disposed in said means and arm.
